if the discussion violates TIMS rules, it's uncommon but users who make personal attacks including sarcastic remarks aimed at a poster rather than the content, can be outright banned without notice.
locking a thread when it degenerates into members sniping at each other is a soft alternative. also, the rules state that ongoing stale debates turn off readers. the rules basically require TIMS members to agree to disagree. this requirement is stolidly ignored by certain of the TIMS membershp, particularly in the CCSVI forum.
i agree it would be preferable if the pros and cons could be reasonably considered and discussed here.
